any FAA-approved repair facility reasonably acceptable to Lessor for service, repair, maintenance or overhaul work of the Airframe or any Engine or any part thereof or for alterations or modifications in or additions to the Airframe or any Engine to
the extent required or permitted by the terms of this Lease. 

 h. To keep the Aircraft free and clear of all seizures, security interests,

 i. That if for any reason any part of the Aircraft is replaced with a similar part, or any part or attachment is added thereto, no matter by whom
manufactured, the part so replaced or added shall at once become the property of Lessor, to the same extent as all the original parts of the Aircraft, and with the same rights and powers of Lessor in all respects as if such part had been one of the
original parts thereof, and any such part added will be supported by complete records back to the original manufacture date. Any new part placed on the Aircraft shall be free of liens and shall be of same value and utility as the part being
replaced.
